In concrete implementation process, super capacitor can not make its charging voltage surpass the SC service ceiling value of regulation.If surpass this higher limit, super capacitor will be damaged, can utilize to greatest extent for the capacity that makes super capacitor simultaneously, generally in use, the capital is set in the maximum voltage of super capacitor near near its maximum use value, therefore need carry out voltage control accurately to super capacitor.
When charger charges to super capacitor, the mode with constant voltage floating charge is directly filled in the employing constant current, when the voltage of super capacitor hangs down, use the constant current large current charge, when the voltage of super capacitor during near setting, use the mode of constant voltage floating charge instead, the electric current that the present invention adopts only detects voltage in the constant current charge stage, does not therefore have power loss substantially.When the voltage of super capacitor during near setting, with the intelligent decision charge condition, whether need to determine the energy of releasing then.Its concrete implementation process is as follows:
First resistance R 1, the voltage that second resistance R 2 and 3 pairs of the 3rd resistance R are connected to the super capacitor of first link 101 and second link 102 carries out dividing potential drop, voltage to super capacitor is sampled, high accuracy first reference voltage that provides of the A that sampling is obtained first sampled voltage of ordering and the first controllable accurate source of stable pressure U1 compares afterwards, when the magnitude of voltage of super capacitor surpasses setting, this first sampled voltage can be higher than first reference voltage, make the controllable accurate source of stable pressure U1 conducting of winning, drag down B point voltage value, make the triode Q1 conducting of winning, and then make the Darlington transistor Q2 conducting of winning, the parallel circuits that the 11 resistance R 11 and the 12 resistance R 12 are formed is connected to the two ends of super capacitor, constitutes bleed-off circuit.When the first triode Q1 conducting, can make the LED 1 luminous warning of winning, but the warning of this branch road was used when only being used for close beta.Can control the first Darlington transistor Q2 by the second triode Q3 for the control of leakage current size realizes, why adopt the first Darlington transistor Q2 to be because its cost is lower and this device has amplification, and its upper bound current value is bigger, satisfies the demand of the two-stage type balancing circuitry that the present invention relates to.When the voltage of super capacitor surpasses assigned voltage when very big, the collector electrode of the second triode Q3 is given the base stage feedback first control voltage of the first Darlington transistor Q2, makes leakage current raise; When the voltage of super capacitor surpasses assigned voltage hour, the collector electrode of the second triode Q3 is given the base stage feedback second control voltage of the first Darlington transistor Q2, makes leakage current reduce, and has realized the purpose of dynamic adjustment leakage current.According to the maximum charging current of system, set maximum leakage current simultaneously.
After the overvoltage of super capacitor is released, the voltage of super capacitor still surpasses setting, illustrate that the overvoltage fault has taken place for this super capacitor or foregoing circuit, use warning circuit unit 50 output alarm signals this moment, its process is: by the 13 resistance R 13, the 14 resistance R 14,15 pairs of these overvoltage of the 15 resistance R are carried out dividing potential drop, overvoltage to super capacitor is sampled, high accuracy second reference voltage that provides of the C that sampling is obtained second sampled voltage of ordering and the second controllable accurate source of stable pressure U2 compares afterwards, when the magnitude of voltage of super capacitor surpasses setting, this second sampled voltage can be higher than second reference voltage, the second controllable accurate source of stable pressure U2 conducting, drag down D point voltage value, make the 3rd triode Q4 conducting, and then make the luminous warning of the second light-emitting diode D1, this alarm signal will be by the 3rd link 501 and 502 outputs of the 4th link.
In concrete implementation process, the first controllable accurate source of stable pressure U1 and the second controllable accurate source of stable pressure U2 can use TL431, the first triode Q1 and the 3rd triode Q4 can use MMBT5401, and the first Darlington transistor Q2 can use MID122, and the second triode Q3 can use MMBT3904.
The two-stage type balancing circuitry that is used for the super capacitor module that the present invention relates to can accurately measure the voltage of each super capacitor; Charging process for super capacitor, only at the voltage of super capacitor during near setting, just can cause some energy losses, because at the voltage of super capacitor during near setting, with the intelligent decision charge condition, determine whether need the energy of releasing then, in the process of releasing, can also dynamically adjust leakage current, thereby make the energy consumption of overall plan reduce greatly compared to prior art; At false alarm situation of the prior art, that is: as long as charging voltage reaches setting, will carry out: start leadage circuit on the one hand, send an overvoltage signal to system immediately on the other hand, thereby need artificial intervention, see whether super capacitor is damaged or other failure condition, the present invention has adopted warning circuit unit 50, make the enabling signal of bleed-off circuit and external alarm signal separate, have only and to have taken place to release and the magnitude of voltage of super capacitor still surpasses under the situation of setting, just explanation is that the overvoltage fault has taken place really, thereby greatly reduces the probability of false alarm.Because just release sample circuit unit 10, the contrast circuit of releasing unit 20, release switching circuit unit 30 and leadage circuit unit 40, the possibility that above-mentioned false alarm takes place is very high, will report to the police as long as charging arrives basically.
The two-stage type balancing circuitry that the present invention relates to no matter adopt which kind of mode, is handled as long as above-mentioned leadage circuit unit 40 separated with warning circuit unit 50, thereby is reached the purpose that prevents false alarm, all belongs to protection scope of the present invention.
